Actually, the so-called "gay rights" movement would love to rid itself of the association with the above mentioned group. They certainly are not welcomed.
Homosexuality and child molestation: the link, the likelihood, the lasting effects
"... Furthermore, some suggest that public disavowal of NAMBLA by homosexual groups is a smokescreen. David Thorstad, a founding member of NAMBLA and former president of New York’s Gay Activists Alliance, says homosexual activists have supressed pedophilia in order “to sanitize the image of homosexuality to facilitate its entrance into the social mainstream.”..."
The Overhauling of Straight America
"... (2) Portray gays as victims, not as aggressive challengers. In any campaign to win over the public, gays must be cast as victims in need of protection so that straights will be inclined be reflex to assume the role of protector. If gays are presented, instead, as a strong and prideful tribe promoting a rigidly nonconformist and deviant lifestyle, they are more likely to be seem as a public menace that justifies resistance and oppression. For that reason, we must forego the temptation to strut our “gay pride” publicly when it conflicts with the Gay Victim image. And we must walk the fine line between impressing straights with our great numbers, on the one hand, and sparking their hostile paranoia -- “They are all around us!” -- on the other.
A media campaign to promote the Gay Victim image should make use of symbols which reduce the mainstream’s sense of threat, which lower its guard, and which enhance the plausibility of victimization. In practical terms, this means that jaunty mustachioed musclemen would keep a very low profile in gay commercials and other public presentation, while sympathetic figures of nice young people, old people, and attractive women would be featured. (It almost goes without saying that groups on the farthest margin of acceptability, such as NAMBLA, must play no part at all in such a campaign; suspected child-molesters will never look like victims).
Now, there are two different messages about the Gay Victim that are worth communicating. First, the mainstream should be told that gays are victims of fate, in the sense that most never had a choice to accept or reject their sexual preference. The message must read: “As far as gays can tell, they were born gay, just as you were born heterosexual or white or black or bright or athletic. Nobody ever tricked or seduced them; they never made a choice, and are not morally blameworthy. What they do isn’t willfully contrary -- it’s only natural for them. This twist of fate could as easily have happened to you!”..."
